I arranged for a car rental through EconomyBookings.com in August specifying that our arrival at Heathrow airport would be just before midnight hence car collection would be at that time. All this was specified on the booking confirmation I received. No point in saying that we arrived at Thrifty Car Rentals near Heathrow Airport to find out that they were shut. I called EconomyBookings as well as emailed them the next day and was promised an investigation and a reply within 7-21 business days. That was in early September. They have not replied and have not received a refund either. I am totally dissapointed by their inefficiency and inability to behave professionally.
